With its venerable mansions, spacious gardens and ornamental iron, Moss Avenue stands as one of the city’s grandest — and most historic — thoroughfares.

It’s also an upscale setting for a flea market, now known as the Moss Avenue Antique & Collectible Sale. The sale, in its 35th year, does more than provide an opportunity for browsers to pick up bric-a-brac: it’s the sole source of income for the Moss-Bradley Residential Association.

Moss Avenue is closed to car traffic that day, but the Peoria County Sheriff’s Office Posse patrols on horseback. Food vendors are a part of the mix, as is the convivial spirit between residents and visitors.

“Who eats onion rings at 9 in the morning? We do on Moss Avenue on the day of the sale,” says Moss Avenue resident Dan Callahan. “Who leaves their front door unlocked for eight hours while total strangers walk by? We do — no problem.”

It’s free to peruse the merchandise. Callahan says a frugal day of entertainment can be had for $5: “That covers food and a doodad.”

The 35th annual event will be held this year from 8 a.m. to 3 p.m. June 13.
